LITTLE ROCK (AP) — A man sentenced to death for a 1993 killing at a Little Rock laundry asked the Arkansas Supreme Court on Thursday to order a new sentencing hearing on grounds the jury didn't consider evidence that he had a troubled childhood.

Terrick Nooner, 42, was convicted of killing Scot Stobaugh, 22, of Russellville during a robbery. A second person also was convicted and sentenced to life in prison without parole.

Josh Lee, Nooner's attorney, cited a decision by the high court in December 2011 in which another condemned inmate, Frank Williams, was granted a new sentencing hearing for the same reason.

At the time, jurors could check a box on the verdict forms that indicated there was no mitigating evidence, which jurors did in Nooner's case. The form has since been changed.

"It can only assume the jury eliminated the mitigation from consideration," Lee said. "It's impossible to tell whether the jury considered the mitigating evidence."

Associate Justice Donald Corbin said there was surveillance video evidence in the case that allegedly showed Nooner and Robert Rockett walk into a room with the victim, where he was later found with a fatal gunshot wound.

"Why would they (jurors) want to listen to anything else after that," Corbin asked.

Lee noted that prosecutors didn't rebut testimony about Nooner being taken from his childhood home because he was abused and that he was later treated in a psychiatric unit.

Senior Assistant Attorney General Kelly Bright asked justices to deny Nooner's resentencing request, which would have the effect of overturning the precedent they set in Williams' case.

"It's not a violation of fundamental error," Fields said.

Lee said it would be inconsistent to grant relief for Williams and not for Nooner.

A circuit judge last week blocked further executions by ruling the state's 2013 execution law is unconstitutional. That case also is expected to wind up before the Arkansas Supreme Court.

Williams was sentenced to die for the 1992 shooting death of a farmer in southern Arkansas.

Standard verdict forms were changed so that jurors now only state whether they were swayed by mitigating evidence. Lee told justices he didn't think a ruling in Nooner's favor would lead to more similar appeals as juries generally indicated that they'd considered mitigating evidence.
